Chen Xu rode a horse and hummed a small song and left the blacksmith shop, and his mood suddenly became very good.

Gongshu won was a complete accident for him.

What was even more surprising was that someone in the Qin Dynasty could already refine cracked iron with few impurities and very low carbon content.

Although the claim that Gongshusheng has not been confirmed and verified in later archaeology, it is not surprising that according to the current developed copper and iron smelting technology and scale of Daqin, it is not surprising that it has appeared, because bronze processing also begins to refine semi-melting copper blocks, and then add lead and tin to make an alloy with a relatively low melting point. Moreover, many copper and iron in the ore are associated ores, such as the most common chalcopyrite, which is a mixture of iron and copper. When smelting, only copper is left after the iron is removed by the slag. Therefore, the iron

It was found that it was actually about the same period as copper. It was not because smelting iron required a higher temperature, and craftsmen did not find a way to reduce the melting point like bronze, so iron had not been popularized on a large scale. However, at this time of Daqin, many agricultural tools were already made of cast iron, and there were even weapons-level iron weapons, but the number was very small. The main reason was that as Gongshusheng said, the smelting cost was too high, which was not worth the cost for the workshop owner, so naturally it could not be promoted.

In nature, iron ore has much richer reserves than copper ore and has a wider source. Therefore, once steel is successfully refined, bronze will soon withdraw from the stage of history.

As long as we have cooked iron, we can say that it will be more than half of the successful manufacturing of high-quality carbon steel weapons.

It is not easy to get out the carbon in pig iron, but it is still very easy to add it.

When calcining the iron block, sprinkle a layer of iron ore powder and repeatedly forge it after the surface melts, or even sprinkle some iron powder directly after the pig iron melts into juice and stirs repeatedly to increase the carbon content. After the slag is cooled, it is carbon steel, but the carbon content in this process is not easy to control. It is not hard enough when it is low, and it is not strong enough when it is high. Therefore, in this era when smelting is basically based on perception and experience, it is very difficult to make a furnace of qualified high-quality carbon steel every time. An experienced craftsman is completely a treasure, and once it is hung, it will suffer serious losses.

Therefore, for Chen Xu, Gongshu won was of great value and deserved good courtesy. So he found You Jiao Liu Po ​​and decided to implement Gongshu won's treatment first so that he could have the energy to concentrate on smelting iron.

"Appoint him a widow without a man to take care of his daily life? Why?" Liu Po's tongue was hanging outside in surprise and almost couldn't shrink back.

"Well, Gongshusheng is a master of smelting copper and iron. His future achievements are limitless. Therefore, he must first solve his food, accommodation and life problems, otherwise he will not be able to feel at ease. By the way, go to the warehouse to find a cow to get two thick and thin linen cloths, and send them to five stones and 300 yuan."

"Lidian, isn't your care a little too much? He didn't even do it..."

"Tell me more, otherwise you can help me smelify the iron?" Chen Xu said angrily.

"Ah, I...I can't do this!" Liu Po ​​said quickly.

"I won't say anything, think about it now!"

Liu Po ​​had no choice but to lower his head and hesitate for a while, and then said: "The 23-year-old Widow Xu, a man from Zhendongtou, has never come back after being recruited and fought four years ago. He is quite handsome and has a good figure..."

"Have you ever slept?" Chen Xu said with a few thrusts.

"Uh, no!" Liu Po ​​quickly shook his head vigorously, "Widow Xu is the niece of Yubu Xu's doctor. Because several thugs in the town like to come to harass her, she... she... invited me to have a few meals. Don't think too much about it, I just think she is pitiful... If the adults think it's inappropriate, I will arrange for other families!"

Do you think I believe it if I say this!

Chen Xu rolled his eyes hard, but there are many such bullshit things in the town, there are not enough men and too many widows, and men like Liu Po ​​who are powerful and powerful, look powerful and powerful, are rare like treasures. Therefore, all widows want to seduce them because it is really not easy for a woman to live in such a fucking era with one or even a few children. It has nothing to do with etiquette, integrity and shame, just to survive. So even if Chen Xu knows this, he can't control it. No matter how good it is, those widows will draw circles at home every day.

"You are willing to bear it?" Chen Xu said with a lip silence.

"Lidian, I... I really have nothing to do with her!" Liu Po ​​stammered, looking at Chen Xu's contemptuous eyes, and finally said with an old face red: "No matter how, I, Liu Po, are still a man, I can't give her a complete home, but I still have to leave a way for her future life. I can't continue like this for ten or twenty years. Since you value Gongshu so much, he will definitely make a name for himself in the future. I feel relieved that Widow Xu will follow him!"

"Remember, if someone really plans to live a good life, don't sneak up on the windows in the middle of the night, otherwise I will know, hum!" Chen Xu snorted coldly.

"Don't worry, Lidian, absolutely not, absolutely not, she is really pitiful!" Liu Po ​​promised quickly.

"Okay, you can arrange this matter, but you have to win the opinion of Widow Xu. If she disagrees, don't force it. At the same time, tell her that Gongshusheng's life must be taken good care of. If the family is uneasy and ruins my big trouble, I will not spare her!"

"Don't worry, Lidian, I'll talk to her now!" Liu Po ​​nodded repeatedly.

Seeing Liu Po ​​riding to Widow Xu's house on a horse, Chen Xu couldn't help but sighed with a dark face. Damn, what are the messing things I do, I have to worry about such things. It's so fucking.

But overall, this is a fucking era, and if history cannot change, it will be even more fucked in twenty years. After Liu Bang came to power, there were more women and fewer men, so a single tax was issued, and young girls were rushing to get married and become mistresses, and the fate of women was even more miserable.

In the pottery workshop, Gao He was busy working next to a small earth kiln built by a few helpers.

This small earth kiln is only two meters high. It is covered with thick yellow mud on the outside, and the inside is refractory bricks. The inner wall is covered with a layer of clay mixed with wood ash. Below is a coal-burning earth stove. At this time, the fire is raging, and a wave of heat is emanating from the top of the sealed earth kiln. There is a half-foot-sized window on the earth kiln. Through the window, you can see more than a dozen pottery bowls and pottery cups made of Guanyin soil are placed on layers of refractory bricks. Under the scorching of the fire, it is a slight white light.

Chen Xu was still a few meters away from the earthen kiln, and he could feel a hot air coming towards him.

"How is the fired effect?" Chen Xu asked after saying hello.

"The mud billets made last time were burned into a kiln, and most of them were cracked, but there were still two intact. I'll show you it's incredible. They were as white as white jade." Gao He was so excited that he ran to the pergola and took out two smooth porcelain bowls and handed them to Chen Xu.

Chen Xu took two porcelain bowls and looked through them. He bought them coldly, smooth and white, and even had a crystal clear texture of bone porcelain, which was not much different from the pure porcelain seen in later generations. However, these two bowls still had many cracks and some deformations. Due to the flaking, there were still circles of traces on them. This way, there was still a big difference from the porcelain Chen Xu wanted.

"Lidian, although this white clay is delicate enough, it is not strong enough. The carcass is too thin and it is slightly deformed during drying. Moreover, because it was the first time to fire, the furnace temperature was not well controlled. Most of it cracked and broken when it was out of the kiln, so I slightly changed the formula of the clay..." Gao He quickly explained to the side.

"Change the formula! How to change the formula?" Chen Xu asked in surprise.

"I added some fine clay to the white clay and then pulled the clay into the clay. The clay made is much stronger. It will be left to dry for a few days before it is fired this morning. After about two hours, the fire will be stopped and the kiln will be released tomorrow!"

"Okay, I'll see you tomorrow! I'll take these two bowls first!"

Chen Xu left with Wang Wu and others with two bowls, then rode around the town for a while and checked, then got a jar of tea tree fruit oil in the sugar winery and returned to Xiaohe Village.

In the past half month, he has been to Qinghe Town and Xiaohe Village in total four times. However, this time he has gained the biggest harvest. Not only did he get the first edible tea tree fruit oil in Chinese history, but he also got the first batch of porcelain in the true sense of China. Although it looks bad, it is undoubtedly real porcelain. At the kiln temperature of more than 1,000 degrees produced by coal combustion, kaolin completely melted and merged into one, turning into a jade-like porcelain. Therefore, he decided to take these two porcelain bowls home and preserve them well. After he died of old age, he would let his descendants put them in the coffin as a souvenir. He also used bamboo abbreviation to write the notes made by Qinghe Town, Chi County in the winter of the 27th year of Qin Shihuang, in order to be worshipped by those who dig graves and archaeologists later.

However, what made Chen Xu most happy today was that he found Gongshusheng, a craftsman who was proficient in smelting copper and iron. If nothing unexpected happens, he will know the result in at most two days. Once the steelmaking method is successful, Daqin will no longer be the Daqin in history.

The next day, the weather became even colder, and the north wind blew, and the earth was shaking. Chen Xu took advantage of the fact that it was not snowing yet and then went to Qinghe Town.

The second batch of porcelain in the pottery workshop has been released from the kiln. After changing the formula of clay, this time it was very successful. More than ten pieces of porcelain were basically intact. Some of them had fine cracks, but they were still intact. However, the fired porcelain was not snow-white, but gray-white. Because it was fired at high temperature, clay and kaolin all melted and merged together, becoming a complete one. However, because the melting temperatures of various components in clay and kaolin were different, the surface was slightly rough, which was similar to the coarse porcelain bowls common in rural areas in later generations.

But it is undeniable that this is the first batch of intact porcelain on the earth that can be practical in a strict sense.

This is an epoch-making milestone success.
